Grades 9–12

The High School Math Circle, also known as the Advanced Math Circle, is for students in grades 9–12. Each week, a different mathematician leads the session, exposing students to fun, creative, or challenging concepts that go beyond what they're likely to see in their ordinary school classes.

A lecturer writes on a chalkboard as students look on.
